Rapid BRDF Measurement Using an Ellipsoidal
... dome mirror with a projector. The system can measure dense BRDFs without any mechanical drive. Because a target material cannot be observed from the surface normal direction owing to occlusion, a mechanism was provided to fill in the missing data using a zonal basis function. We, on the other hand, p ...

MICROSCOPY I: BRIGHT
... As light waves enter a medium from the air, they are slowed down, or retarded. On reemerging the light waves assume their original velocity. Since formed elements in living cells, such as chromosomes, generally have a higher refractive index than the surrounding cytoplasm, light passing through them ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
